To run and debug a Dart Web application in a browser, you either need to use the Dartium browser
or have the Dart code translated into JavaScript.

Most browsers that work with JavaScript code do not natively process Dart code. The only exception is Dartium.
This dart-oriented version of Chromium contains a built-in Dart VM and therefore can run Dart code directly.
To be executed in any other browser, Dart code has to be compiled into JavaScript.

With the pub tool,
the compilation is performed through the pub serve action
using the built-in dart2js compiler.

You can run Dart Web application in any browser, while debugging is supported only in Dartium and Chrome.
To run a Dart Web application you just need to open the starling HTML page in the browser of your choice.
Debugging a Dart Web application is initiated through a run configuration of the type JavaScript Debug.

Integration with the native Dart static analysis engine:
all inconsistencies and potential problems are reported in the dedicated
Dart Analysis Tool Window
with the possibility to navigate to the fragment of the source code where the problem was detected.
